Change in coreboot[master]: mb/emulation/qemu-armv7: Add MMU support
by Patrick Rudolph (Code Review) 07 Aug '23

Patrick Rudolph has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/44394 ) Change subject: mb/emulation/qemu-armv7: Add MMU support ...................................................................... mb/emulation/qemu-armv7: Add MMU support Extend the memlayout and configure the MMU in the bootblock. While there's no real benefit on emulated machines, it alignes the qemu mainboard with real hardware. Tested using uImage/FIT. Still able to boot into GNU/Linux 5.5.

Change in coreboot[master]: mb/google/volteer: Implement variant_devtree_update for volteer sku's
by Shaunak Saha (Code Review) 07 Aug '23

07 Aug '23

Shaunak Saha has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/44261 ) Change subject: mb/google/volteer: Implement variant_devtree_update for volteer sku's ...................................................................... mb/google/volteer: Implement variant_devtree_update for volteer sku's HybridStorageMode FSP UPD needs to be set only for optane storage. Enabling HybridStorageMode causes some extra delay in FspSiliconInit due to HECI command and hence is avoided for NVMe and SATA scenerios. This change disables "HybridStorageMode" by default from baseboard devicetree. Any volteer variant which is using optane should enable "HybridStorageMode" from the override devicetree file.This change also provides an implementation of variant_devtree_update() for volteer that enables HybridStorageMode for SKU ID = 3 and 5. BUG=b:158573805 TEST=Verify HybridStorageMode is disabled when SKU ID != 3 or 5 and enabled for those 2 sku's only.

Since there can be two different versions and/or configurations, would fallback/config and normal/config make more sense?

Change in coreboot[master]: WIP: Hash RAM contents on S3 entry and verify on S3 resume
by Raul Rangel (Code Review) 07 Aug '23

07 Aug '23

Raul Rangel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/42890 ) Change subject: WIP: Hash RAM contents on S3 entry and verify on S3 resume ...................................................................... WIP: Hash RAM contents on S3 entry and verify on S3 resume I used murmur3 since it's supposed to be fast. Though I don't think the license is really compatible. The ram_hash code still needs some refactoring to reduce duplication and to add the ability to handle unaligned blocks. BUG=b:159081993 TEST=Boot trembyle and see no verification failures.

Change in coreboot[master]: WIP: lib: Add murmur3 algorithm for RAM hash
by Raul Rangel (Code Review) 07 Aug '23

07 Aug '23

Raul Rangel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/43301 ) Change subject: WIP: lib: Add murmur3 algorithm for RAM hash ...................................................................... WIP: lib: Add murmur3 algorithm for RAM hash This is the murmur3 algorithm from https://github.com/PeterScott/murmur3. I'm not sure we can even include this since it's public domain. We might need to use another hash algorithm. I picked it because it's supposed to be fast. I didn't cleanup the code at all. This is why -Wno-implicit-fallthrough was added to the CFLAGS. BUG=b:159081993 TEST=Suspend trembyle and see hashes being generated.

Change in coreboot[master]: soc/amd/picasso: Add support for RAM hash
by Raul Rangel (Code Review) 07 Aug '23

07 Aug '23

Raul Rangel has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/43302 ) Change subject: soc/amd/picasso: Add support for RAM hash ...................................................................... soc/amd/picasso: Add support for RAM hash This CL allocates a region in EARLY_DRAM to store the RAM hashes. It also introduces a hard coded memory map based on the current e820 map. In the future we could maybe automate the generate of the hash_ranges. Until now we will need to keep it updated. To enable, add the following to your .config: CONFIG_ENABLE_RAM_HASH=y Hashing RAM from the SMM handler is pretty slow compared to trying it in bootblock. Not sure if the OS has reset the MTRRs.
